Section 343.2. Rules of evidence; corroboration of accomplice testimony

1.
  A respondent may not be found to be delinquent upon the testimony of  an
  accomplice  unsupported by corroborative evidence tending to connect the
  respondent with the commission of the crime or  crimes  charged  in  the
  petition.
    2.   An  "accomplice"  means  a  witness  in  a  juvenile  delinquency
  proceeding who, according to evidence adduced in  such  proceeding,  may
  reasonably be considered to have participated in:
    (a) the crime charged; or
    (b)  a  crime  based  on the same or some of the same facts or conduct
  which constitutes the crime charged in the petition.
    3. A witness who is an accomplice as defined in subdivision two is  no
  less  such  because  a  proceeding, conviction or finding of delinquency
  against him would be barred or precluded by some  defense  or  exemption
  such  as  infancy,  immunity  or  previous  prosecution  amounting  to a
  collateral impediment to such proceeding,  conviction  or  finding,  not
  affecting  the  conclusion  that  such  witness  engaged  in the conduct
  constituting the crime with the mental state required for the commission
  thereof.
